利用2003年2月至2009年4月期间在吕宋海峡附近海域由Argo剖面浮标观测的温、盐度资料, 对该海域的水团分布及季节变化特征进行了探讨。结果表明, 在120.5?—122.75?E、19?—23?N范围内, 水团特征介于南海水和北太平洋水之间, 而19?N以南区域的水交换并不显著。北太平洋热带水(NPTW)和北太平洋中层水(NPIW)通过吕宋海峡入侵南海的趋势在夏季较弱。秋季, NPTW入侵南海的趋势增强, 而到了冬季, 受东北季风控制, 北太平洋水的入侵程度最强, 然而并无NPIW进入南海的迹象。值得指出的是, 整年没有发现明显的NPIW进入南海, 而南海中层水可以通过海峡流入太平洋, 其强度在秋、冬季节达到最大。

The Luzon Strait is located between Taiwan and Luzon islands, connecting the Philippine Sea and the South China Sea. The characteristics of water mass distribution and its seasonal variation in this region were discussed using the Argo temperature and salinity data from February 2003 to April 2009. The analysis suggested that in the area of 120.5º?122.75ºE and 19º?23ºN the water mass has the properties between the South China Sea Water and the North Pacific Water; in the area south of 19ºN, the water exchange is not significant. The intrusion of the North Pacific Tropical Water (NPTW) and the North Pacific Intermediate Water (NPIW) into the South China Sea is relatively weak in summer. The intrusion of the NPTW is strengthened in fall and winter. When the northeasterly monsoon becomes fully developed, the intrusion reaches its most. However, there is no evidence of the NPIW water flowing into the South China Sea. It should be pointed that there is no indication that the NPIW enters the South China Sea in any seasons, while the intermediate water from the South China Sea can flow into the Pacific through the Luzon Strait, reaching its maximum strength in fall and winter.
